BUCKLE.

Specification of Letters Patent.

Patented Aug. 13, 191s.

Application filed March 18, 1916. Serial No. 85,109.

To all Awhom it may concern.'

Be it known that I, ELMER B. MCCONAHY, a citizen of the United States, residing at Mulino, in the county of Clackamas and State of Oregon, have invented certain new and useful Improvements in Buckles, of which the following is a specification.

This invention relates to buckles and has for its obj ect to provide a buckle that is very simple in construction, easily fastened, and when fastened holds the parts securely together but which may be quickly loosened when desired and the parts disconnected.

Another object of the invention is to provide a buckle in which the fixed end of the strap is secured to a pivoted loop from which a tongue projects, and said loop being so connected to the frame of the buckle that when the free end of the strap is connected to the tongue, the stress on the strap tends to hold the buckle in closed position, but upon a pull upon the free end, the parts of the buckle readily separate and permit said end to become disengaged thereby giving aV quick, easy and free opening or release for the free end of the strap.

In the accompanying drawing,

Figure 1 is a perspective view of the improved buckle in released position, and,

Fig. 2 is a horizontal sectional View thereof as appears when in closed position and the strap Linder tension.

Referring to the drawing by numerals 10 indicates the frame of the improved buckle formed with two parallel curved side bars 11 joined together at their ends by straight portions 12. Projecting outwardly from the concaved side of each curved side bar 11 and at the center thereof, is an ear 13. Pivotally connected to the ears are the ends of a yoke 14, the straight connecting meinber 15 of which has a tongue 16 rigid therewith projecting outwardly from the center thereof, the axis of which preferably lies in a plane passing through the centers of the pivots 17 that secure the loop to the ears 13. The yoke 14 may swing freely from end to end of the buckle frame being arrested or limited in its movement by the tongue 16 striking one or the other of the straight bars 12.

Looped around the bar 15 of the yoke 1 is a strap 18, the end of which is secured to the bar 15 by stitching 19 through the strap back of the bar as shown, a slot 20 being made in the strap to permit the tongue 16 moving freely as Vthe yoke swings from end to end of the buckle. The opposite or free end 21 of the strap is provided with the usual perforations and if desired these perforations may be reinforced by eyelets 22.

In use the strap 18 is placed around the article to be fastened and the free end 21 passed under the bar 12 at the front of the buckle frame, and the strap pulled as tightly as desired in the usual manner.Y Under the tension of tightening the strap if the yoke 141 be left free, it will swing rearwardly until the tongue 16 abuts against the rear bar 12 of the buckle, then when the strap is to be fastened, the yoke must be moved in the opposite direction until the tongue engages one of the holes in the free end of the strap, after which the yoke is further swung forwardly until the tongue engages the front bar 12. In this position, the end of the strap attached to the yoke 141 will be brought forward a short distance thus increasing the tension on the strap, which tension extending in a line through the pivots 17 or behind them will hold the buckle tightly fastened, further security being provided by slipping the free end of the strap beneath the rear' bar 12 of the buckle, as in Fig. 2.

To release the buckle, the free end of the strap is withdrawn from behind the rear bar 12 and brought to the position indicated in dotted lines in Fig. 2, then by means of a steady pull or jerk on the free end of the strap, the tongue, and the yoke to which it is attached, will swing outwardly thereby moving the bar 15 of the yoke outside of the axis of the pivots 17 to such an extent that the tension on the strap will cause a further rearward movement of the yoke until the tongue 16 is withdrawn from the hole in the free end of the strap, the tongue moving to the position represented in dotted lines in Fig. 2, or further if the tension be great enough until the tongue strikes the rear bar 12. In this position of the tongue the free end of the strap may be easily withdrawn from the buckle. It is evident that the buckle herein described is a very etlicient one, simple in construction, cheaply made, and quickly connected and disconnected and when connected securely holds the free end of the strap, the arrangement of the removable parts being such, the greater extension or stress upon the strap. the more secure are the parts held together.

From the foregoing description taken in connection with the accompanying drawing, it is thought that the construction and operation of the device will be clearly under stood, and while I have herein shown and described certain specic embodiments of my invention, I do not wish to be limited thereto eXcept for such limitations as the claims may import.

I claim:

l. In a buckle, a rectangular frame formed with parallel side bars convexly curved toward the outer face of the buckle, a U-shaped yoke centrally pivoted at its ends to the concave sides of said side bars, and a tongue rigid with the cross bar of said yoke and projecting outwardly therefrom in a plane passing` through the pivotal axis of the yoke'.

2. In a buckle, a rectangular frame formed with parallel side 'bars convexly curved to ward the outer side of the buckle, a yoke formed with a straight bar extending across direction to said arms, said yoke and tongue 30 adapted to swing as a unit to bring the tongue into contact with the opposite ends of the rectangular frame and shift the position of the attached strap to tighten or loosen said strap.

In testimony whereof l affix my signature in Vpresence of two witnesses.

ELMER B. MCGONAHY.
